Description
Everything below comes from what Atlas publishes about this impregnant and from the live listing — which turns out to be less than the previous version of this page claimed. Atlas Bejca 06 Teak sits at the end of the wood-effect sequence in the concrete effect render range at Renders World, and the honest specification is short, so the ordering arithmetic below matters more than usual.
Where a Teak Bejca Coat Belongs in an Atlas Wood-Effect Facade
Atlas Bejca Sealer Teak 4L is the semi-transparent staining impregnant Atlas specifies over Cermit WN decorative render, covering 4–5 m² per litre per coat and turning a stamped mineral surface into a timber-board facade. The scope Atlas states is broader than the wood effect alone.
- The primary role: a thin, coloured protective coating on Atlas Cermit WN decorative render imitating the texture of natural wood — the stage that supplies both the timber colour and the protective film.
- Named as a system component: Atlas states the product is part of thermal insulation systems, and the distributor listing names those as ATLAS ETICS and ATLAS ROKER. That is manufacturer system membership, and nothing on this page describes it as a certified or approved product.
- Other substrates Atlas allows: concrete, all types of mineral render whether smooth or textured, gypsum render and putty, and gypsum plasterboard — which is what makes one tin usable on interior feature work as well as elevations.
- One of ten shades: 06 Teak sits in a palette running from 01 Alder through 09 Ebony to 10 Acacia, so the shade is a design choice made across a documented range rather than a one-off tint.
Read that list as a boundary. The coating is documented over Cermit WN and over ordinary mineral and gypsum backgrounds; where a project wants the timber read, the stamped Cermit WN beneath it is what creates the grain, and the Bejca only colours what the stamp has already formed.
What Atlas Documents About This Impregnant — and What It Does Not
The characteristics Atlas publishes are chemical and behavioural rather than numerical, and each one has a practical consequence on a stamped surface.
- Binder: a mixture of low-molecular polymer dispersions and silicone resins — the polymer content is what Atlas credits for coat elasticity and resistance to weather, so the film moves with the render panel instead of sitting rigid over it.
- Strongly hydrophobic: Atlas attributes this to the added silicone resins, which reduce water absorption of the coating and reduce the adhesion of dust and dirt particularly in the recesses of the render — the grooves of a wood stamp being exactly where soiling would otherwise collect.
- Colour stability: specially selected semi-transparent pigments with high UV resistance, supplemented with small additions of inorganic pigments, which Atlas states keeps colours stable for years. No figure in years is published, and none is stated here.
- Consumption: 4–5 m² per litre at a single coat, with Atlas adding that the exact consumption is established by a trial on the rendered substrate itself.
Four figures that appeared on the previous version of this page are absent from every source retrieved this session: a density, a drying time between coats, an application temperature band and a rain-resistance interval. Atlas's own technical sheet is hosted on a server that refuses automated retrieval, and it was attempted twice this session without success. Those numbers are therefore omitted rather than repeated — the printed tin and the sheet supplied with the delivery carry them, and they are the versions to work to on site.
Ordering the 4 Litre Tin: Coverage Arithmetic and the Trial Panel
This is the part of the audit worth acting on, because the arithmetic has changed. Renders World lists the tin at £69.00, in stock, August 2026, and the sourced consumption gives a materially tighter coverage than this page previously showed.
| Calculation | Operands and result |
|---|---|
| Coverage per tin, one coat | 4 L × 4–5 m²/L = 16–20 m² |
| Material cost per m², one coat | £69.00 ÷ 16–20 m² = £3.45–£4.31/m² |
| Coverage per tin, if two coats are specified | 16–20 m² ÷ 2 = 8–10 m² of finished facade |
| Tins for a 40 m² elevation, one coat | 40 ÷ 16–20 = 2.0–2.5, rounded up = 3 tins |
| Previously published figure | 26–40 m² per tin — no source found; omitted |
Order against the lower band. The difference between the two figures is roughly a doubling of the tins a facade needs, and a job quoted on the higher number would run short partway up the scaffold. Atlas's instruction to establish consumption by trial on the actual rendered substrate is the resolution: a stamped test panel, coated and measured, converts these ranges into a number for your specific render porosity and stamp depth before the order is placed. The number of coats is likewise a finish decision that no source retrieved this session fixes.
Applying Teak Bejca Over Cured Cermit WN
The sequence the collection documents runs render, mould release, stamp, then colour — the full method across the Atlas timber system sits in the concrete effect render application guide, and the comparative view across the Bejca shades is in the guide to sealers for concrete effect renders. Two points belong specifically to this tin.
- Coat the trial panel first, and keep it. Since Atlas ties exact consumption to a substrate trial, the panel doubles as the shade approval: 06 Teak is semi-transparent, so the cured colour of the Cermit WN beneath it contributes to the final read, and the panel is what a client signs off against.
- Keep the pigment in suspension. Semi-transparent pigment systems settle in the tin, and the fix is simply to re-stir at intervals through the job so the last panel matches the first. This is trade practice rather than a manufacturer instruction, and it is stated here as such.
- Substrate preparation stays with the priming stage. Where the background is not freshly stamped Cermit WN, Renders World holds that stage in the exterior render primers range, and the priming product is chosen for the background rather than for the sealer.
Working conditions — temperature limits, the interval between coats and how long the fresh film needs before rain — are the figures this session could not source. Take them from the tin before the first coat goes on, and the working day plans itself around them cleanly.
Choosing Between Teak, Walnut and Birch
Renders World stocks three of the ten Atlas shades. No source retrieved this session distinguishes them on any technical property: same product, same binder, same consumption, same substrates. The choice is a tonal one, made against the manufacturer's swatch and the base render colour.
| Shade | Position in the Atlas palette | How the choice is made |
|---|---|---|
| 06 Teak, this tin | Mid-tone, between the pine and rosewood shades | The default warm timber board read on a full elevation |
| 03 Walnut, the darker shade | Darker than teak, above ebony in the range | Chosen where contrast against pale render is the design point |
| 08 Birch, the palest shade | The lightest of the three stocked | Chosen for a pale Nordic read on darker base render |
Specifying Teak Bejca: A Four-Point Check
- Confirm the background is one Atlas names. Cermit WN for the wood effect, or concrete, mineral render, gypsum render, putty and plasterboard for flat work.
- Coat a trial panel and measure it. That converts 4–5 m² per litre into a tin count for your render, which is the number to order from.
- Order to the lower coverage band. Sixteen square metres per tin per coat, with a spare tin held for absorption above expectation.
- Take the working figures off the tin. Temperature, recoat interval and rain resistance are printed on the packaging and on the sheet supplied with the goods.
Where the design moves away from timber altogether, the smooth and brick routes sit alongside this one in the concrete effect render collection, and Renders World stocks Atlas Base Coat Paint 10 L as the tinted base for that side of the range — Atlas does not name it within the Bejca scope, so confirm the pairing on the order.
FAQ — Coverage, Substrates and Shade Choice
How many tins does an elevation need?
Divide the area by 16–20 m² per tin per coat and round up, then multiply by the number of coats the finish calls for. A 40 m² gable takes three tins for a single coat. Atlas asks for a trial on the actual rendered substrate to firm that up, because stamp depth and render porosity move consumption inside the band.
Which backgrounds does Atlas allow it on?
Cermit WN decorative render is the documented primary background, and Atlas additionally names concrete, all types of mineral render whether smooth or textured, gypsum render and putty, and gypsum plasterboard. That range is what lets one shade run from an external elevation through to an interior feature panel.
Does it belong on an insulated wall build-up?
Atlas states the product is part of thermal insulation systems, and the distributor listing names ATLAS ETICS and ATLAS ROKER specifically. That is system membership as the manufacturer describes it; no certificate covering this tin was retrieved this session, so nothing here calls it certified or approved.
Is teak technically different from the walnut or birch tin?
No source retrieved separates them on anything but colour — binder, consumption and substrate scope read identically across the three. Treat the decision as tonal, and settle it on a stamped sample panel where the base render colour shows through the semi-transparent film.
How long does the finish last?
Atlas describes colour stability over years from UV-resistant semi-transparent pigments and a hydrophobic silicone-resin film, without publishing an interval in years, so no lifespan figure appears on this page. Practically, the surface is maintained like any coated facade — periodic low-pressure washing keeps the recesses clear, which is where the silicone content is already working in your favour.
